Morrisville doesn't match the rest of our coverage area. Across the wider Durham service territory the housing stock runs from 1967 to 2006 with a median build year of 1991 - older tract homes with the quirks that come from decades of patch repairs. Morrisville is different. Its median build year sits around 2006, roughly fifteen years newer than that broader figure, and the subdivisions out here went up fast during the late 1990s and early 2000s growth push. With about 11,492 households and a median income of $125,404 - well above the $77,799 figure that covers the full service area - this is production-built suburban construction: two-car garages, steel sectional doors, factory-installed openers with photo-eye sensors as standard, not retrofit. The springs are torsion, centered, and still commonly in their original cycle life rather than three or four replacements deep. That changes what breaks, when it breaks, and what we bring on the truck when we come out this way.
